Family: Asteraceae

Type: Shrubby herbaceous perennial.

Natural Habitat: Native to Mexico and the Southwest U.S, it is well adapted for the Texas Hill Country.

Growth: 2′ to 4′ tall and wide. Attains a naturally rounded mound.

Deer Resistance: Its strong scent tends to repel deer.

Wildlife: Attracts migrating butterflies.

Light Tolerance: Full sun to part shade. This sun lover is a candidate for the hottest site in the garden. Too much shade though may inhibit flower production.

Flowers: One inch bright golden-yellow daisy flowers smother the foliage, especially during a year with abundant rainfall.

Bloom Period: August ’till frost.

Leaves: The bright green, filigreed leaves release a strong fruity-woodsy smell, even when lightly touched.

Water Requirements: Wonderfully drought resistant once established.

Soil Requirements: Prefers fertile, well-drained cultivated soil. Tolerates heavy clay to sandy soil.

Maintenance: Once frost bitten, the finished stems should be pruned close to the ground and freshly mulched.

Planting Instructions: Space plants 4 feet apart. Dig a hole at least two times wider than, but the same depth as the root ball in the nursery container. Sides of the hole should be irregular, not smooth. Remove plant from container, taking care to support the root ball. Loosen exterior roots gently with your fingers. If the plant is root-bound and cannot be loosened by hand, the outer roots may be cut in several places. Lift the plant by the root ball and place into the hole. Backfill hole, using soil that was dug out. Do not add any soil to the top of the root ball. Gently firm the soil with your hands, but do not tamp it down. Place 1-2 inches of mulch over the bare soil around, but not touching the base of the plant.

Watering Instructions: Water deeply after planting to settle soil around roots. Then every 7-10 days, as needed, during the first growing season. Before watering, check for soil moisture at a depth of an inch or two at the edge of the root ball. Skip a watering after a rainfall of ½ to 1 inch. Maintain this watering schedule until the first fall. Reduce watering during the cool fall and winter months. In a “normal” year, no watering may be necessary during the fall and winter, but during a dry period, monthly watering may be needed. Second spring and thereafter: Water monthly only during periods of drought. Once established, natives will survive with little supplemental irrigation. Note: plant will die back most winters and reappear in spring.

NICE! Tip: Use in garden with fall flower colors of blues and purples from such plants as native asters, Mexican bush sage or Blue Mist-Flower. When not in bloom, its soft domed form contrasts well against strong architectural plants such as prickly pear or spiky yuccas.

About the Region

New Braunfels, the location of our Fall 2024 Symposium, straddles both the Edwards Plateau Ecoregion and the Blackland Prairie ecoregion. Interstate 35 divides the city of New Braunfels; its path through the city closely parallels the boundary of these two ecoregions, with the Edwards Plateau on the west side and the Blackland Prairies region to the east. The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our four host chapters (New Braunfels, Lindheimer, Guadalupe, and the Hill Country chapters) are located in one or both of the ecoregions above. However, the eastern portion of Guadalupe County also falls within the Post Oak Savanna ecoregion. Annual rainfall averages 35 to 45 inches, with higher averages to the east. A wide variety of hardwood trees are found, including several species of oaks, elms, and in the Bastrop area, loblolly pine (Pinus taeda). Grasses and forbs dominate in the open savannas, with most common grass being little bluestem. Ranching, agriculture, and fire suppression have allowed woody species to encroach on the once-open savannas.
